DID 532 ZLV Steel 116 Link X-Ring Super Heavy Duty Motorcycle Chain

X-Ring superbike chain made to meet certain manufacturer requirements for strength and durability on today’s high performance machines. DID’s ZLV Chain uses patented X-ring seals. Like O-rings, X-rings function to seal in lubrication and keep dirt out. Where the cross section of an O-ring is circular, the cross section of an X-ring is ‘X’ or cross shaped. This gives the seal additional contact points compared to the O ring, offering superior sealing and protection against dirt and grit getting stuck under the seal. In addition, when under pressure an O-ring becomes squashed and causes friction. An X-ring, when under pressure, diverts this pressure by twisting instead, so an X-ring decreases friction between side plates and reduces power loss by 50% of any other type O-ring chain. DID’s X-rings have 40% greater wear resistance than an O-ring chain and 33 times that of a DID standard chain; this means more resistance to stretching, bowing and warping and smoother handling. With the proper maintenance an X-ring chain will last longer than any O-ring or unsealed chain.
